Metal Grinders=metal alloy in your lungs.

[LIP]

i was trying to get at the point that aluminum would not be able to vaporize at such a low temperature. So it would stay solid, if it gets sucked through the bowl before you dump out the ash, it would probably get stuck in the resin before it entered your mouth. Even if it entered your lungs, these visible flakes are probably big enough that your cilia will eventually brush them out.
that's my logic at least.

I for one think you are 100% right. It's NOTHING to worry about, and as someone said up there ^, if you metal grinder is making THAT much friction, it cant be top end... I have a grass leaf metal grinder and it works perfectly, i love it, and best of all, NO shavings...

What about filters? screens? the pot itself? water in a bong?

There's a lot of things that will stop these few "shavings" from getting into your mouth let alone , lungs.

$130 for a potentially cancerous grinder? I have a coffee grinder that cost me 7 bucks 2 years ago, nothing but fresh tasty weed coming out of that thing, go to the appliance section at wal-mart, they'll get you hooked up.

If I seen metal shavings in my grinder id chuck it to, for what its worth.

...sorry..I am a noob on this subject....why do you grind your weed into dust?..

...seems unnatural to me...??...from a J point of view...old school smoker...

My grinder is made out of human skin, nails and a little bit of bones...no I don't have a skin grinder, I'm talking about my hands .

powder weed is better in bongs in bowls

all you gotta do is spark it once and thats it

i think its better because your keeping as much thc in your bud as possible

[exiled247]

that's why i don't use grinders... i've heard of people talking about metal flakes so i just chose to break it down as much as possible with my fingers...
